Why Do Humans Have No Body Hair. But combining the new study’s molecular evidence of how hair grows with physical traits observed in humans will get us closer to the truth—or at least closer to a fuller, shinier head of hair. Recent findings lay bare the origins of human hairlessness—and hint that naked skin was a key factor in the emergence of other human traits. Smooth, clear skin may have become a signal of health, like a peacock's tail, and could explain why women are naturally less hairy than.

Orangutans, mice, and horses are covered with it, but humans aren't. Something brushing up against hair moves the hair follicles, which send signals to the brain to pay attention. Why we have significantly less body hair than most other. The reason we seem to have less hair: Most human follicles develop what’s known as vellus hair — the fine, barely. This means that the temperature of the brain increases when the body heats up, which can affect brain functions. Hair is an extended sensory tool. The fur also protects the skin from the harmful uv rays of the sun. It coincided with early humans gaining a darker skin pigmentation where body hair previously would have been. No matter what prompted the loss of human fur, one thing is extremely likely:
